Just a brief and (over-)simplified (?) response. Wall
maps/wall-maps/wall maps (what dictates Webster?), from the sixteenth
century on, were composed of multi-sheet woodcut, copper-engraved, or
lithographed (or initially engraved and then transferred to litho
stones) maps/charts printed down on to paper.
Then, if requested - and paid for by the client(s) - colored by hand
to/thru the 19th century; thereafter, with gradual perfection of
chromo-lithographic printing - especially registration - techniques.
Mounting on cloth would, again, be at clients' request and expense.
Application of a varnish for 'protective' [!] purposes was a frequent
extra, along with - notably in 19th and 20th centuries - attachment to a
wooden roller at the top in order that the map might be suspended,
unrolled, and re-rolled when not required: 'CRV' is frequently found in
map catalogs and lists, meaning 'C[loth,] R[olled,] V[arnished]' (or
variations in English thereof, usually explained in said map makers' &
map sellers' catalogs). Alternatively, the insertion of metal-ringed
'eyelets' at top of the wall map, to facilitate suspension of map from
hooks, is found.
The varnish application, of course, became the 'bete-noir' (that's
French . . .), as it discolored with atmospheric pollution and inherent
breakdown of chemical constituents and age (but then we all do, don't
we?).
Doubtless others will supply more contemporary production techniques
(such can be found, e.g., in general printing and publishing trade
journals/periodicals)?
Sincerely,
(Mr) Francis Herbert (ex-Curator of Maps [and wall-maps], RGS-IBG)

Aloha Map folks,
An artist has contacted me asking for general advice on how to reproduce
(the appearance of) wall maps from the early to mid-1900's. Can anyone
point us to literature on how these wall maps were made?
Of particular interest is how the paper map was printed and adhered to
the cloth backing, what kind of cloth was used, and what is that
varnish-like coating often seen on the surface of these maps, etc..
Thank you for your assistance!
